I wrote a very simple example of junit.

I have a Math class

public class Math {

static public int add(int a, int b) {

return a + b;

}

static public int multiply ( int a, int b) {
return a * b;

}

}

and TestMath class

import junit.framework.*;

public class TestMath extends TestCase {

protected void setUp() {

}

protected void tearDown() {

}

public void testAdd() {

int num1 = 3;

int num2 = 2;

int total = 5;

int sum = 0;

sum = Math.add(num1, num2);

assertEquals(sum, total);

}
}
I have the junit.jar in the ant home.When I am trying to
compile my classes I get the following error:
(TestCase(java.lang.String) in junit.framework.TestCase
cannot be applied to ()

Any help?
